428i weird sound...can you figure it out?

The car makes this sound whenever I am rolling or pressing lightly on the gas. After I speed up it stops but it's been annoying. Seems to happen more while I turn the steering wheel but it does it while I go straight too.

Which wheel is it coming from? Have you done a visual inspection of the brakes?

Is this immediately after you start driving? I've got drilled and slotted and they'll chirp like that when cold

You know it's wheels, OP? I was going to guess the blower motor/fan chirping...because the voltage dropped enough that the fan cage wasn't spinning fast enough to balance.

Might be the battery, state of your charge...and not knowing the electronics on this so well, maybe an fsr assuming we have one.

Usually minor things have minor sounds--maybe use a hose or stethoscope to isolate the source? (Guys have taped phones to their cars...not so sure about my doing that, but go ahead...use Gorilla Tape. )
